<p class="p_Normal">“标记到基本”(Mark-to-Base)、“标记到连字”(Mark-to-Ligature)和“标记到标记”(Mark-to-Mark)通常用于向基本字形和连字字形添加变音符号(diacritical mark)。"标记到基本"和"标记到标记"在用法上相同，唯一的区别是"标记到标记"只能使用标记字形。</p>
<p class="p_Normal">利用"标记到基本"、"标记到连字"、"标记到标记"，字形通过锚点相互连接。锚点控制着标记字形与基本字形的互动方式。</p>
<p class="p_Normal">&nbsp;</p>
<p class="p_NoteorTip"><span class="f_NoteorTip">注意：与“标记到连字”查询配合使用的锚点值数，可以通过<a href="glyphproperties.html" class="topiclink">“字形属性”</a>来设置。</span></p>
<p class="p_Normal">每个基本字形都有一个锚点，这个锚点用左边的 X 和 Y 值来定义，并由锚点图标表示：<img style="margin:0;width:0.3125in;height:0.3125in;border:none" src="anchor_indicator.png">。修改这些值会更改标记字形的位置。</p>
<p class="p_Normal">每个标记字形也有一个锚点，用右边 X 和 Y 值来定义。修改这些值会更改标记字形相对于基本字形锚点的绘制位置。</p>
<p class="p_Normal">&nbsp;</p>
<p class="p_Normal">简而言之：</p>
<p class="p_Normal">修改左边的 X、Y ：可更改相对于基本字形的所有标记位置</p>
<p class="p_Normal">修改右边的 X、Y ：可更改相对于所有基本字形的标记位置</p>
<p class="p_Normal">&nbsp;</p>
<p class="p_Normal">如果使用得当，锚点是一个非常强大的工具，可以快速更改几个基本或标记字形组合的位置，而无需修改所有的对子。例如：如果您为大写字形创建一个锚点，为小写字形创建一个锚点，您就可以一次性地更改所有小写字形的标记位置，而不必修改大写字形。</p>

<p class="p_Normal">出现在文本中的组合标记和符号，若不能与一个相符的有效基本字形结合在一起，就被认为是无效的。在 Windows 中，Uniscribe [ Unicode 文字处理器 ] 使用后备呈现机制，即在一个虚线圆圈上来显示这些标记。为了使后备机制正常工作，字体中应包含虚线圆圈 &#9676; 字形(U+25CC)。如果字体中缺少该字形，无效符号就会显示在缺失字形(.notdef)的形状上。</p>
